About this book

Introduction

This thesis describes experimental work in the field of trapped-ion quantum computation. It outlines the theory of Raman interactions, examines the various sources of error in two-qubit gates, and describes in detail experimental explorations of the sources of infidelity in implementations of single- and two-qubit gates. Lastly, it presents an experimental demonstration of a mixed-species entangling gate.

About the authors

Chris Ballance received an MPhys in Physics from Somerville College, Oxford in 2010. He completed his DPhil at Hertford College, Oxford. In 2015 he joined Magdalen College as a Fellow by Examination. His work focusses on using trapped atomic ions to develop the building blocks of a quantum computer.
